Similar to 3M ear muffs.
The rep recommended noise‑cancelling headphones, but this works great. It muffles kids on the bus, plus the train horn and crossing bells near my job. I chose the XL for a tight, effective fit and often add earplugs. Since noise raises stress and affects heart health, this affordable, racetrack‑grade option has been worth it.
Best (quietest) muffs I've even worn. Very comfortable on the head. Maybe offer the XL in some optional colors. Though a standard pair was mistakenly sent, your customer service was very engaging and quickly guided me through verifying it with a pic. The correct replacement was quickly sent out. Thank you.
Still a little bit small for my head. They are wearable but I'm unable to position the headband where I want for the most comfort.
Should put on the website that if needed quickly go to Amazon. The 1 i ordered from the website took a week to deliver and FedEx dropped it off outside in the pouring rain. Got a pair from Amazon in a day. I have hyperacusis and I needed them quickly for work, not a week later. My ears were killing me. I do love how comfortable they are, I just learned to order them off of Amazon and not them due to length of shipping time
Best ones I’ve ever had, best noise reduction, good fit (I’m 6’2”, 210), sturdy, well built, fast shipping, good price.
Finally a pair of muffs that fit my big head!
Better than what I had but wish there were ones that had even higher level of hearing protection
Excellent fit and great sound abatement. Just as advertised.
Fit great and certainly quieter than my other pairs of different brands.
Nice fit
Fast shipping, order correct
Love the earmuffs! They worked great!. Very impressed with them.. Great product!. I really like how comfortable and light weight they were.. I purchased a pair for my grandson and myself..He liked them as well! Thank you for making superior ear protection!
Fit my dads head perfectly and he said they did great. I started taking him to asphalt short track races. We sit near the track because he is in a wheelchair. Great product.
I was happy that these provided the noise reduction I was looking for while operating my lawn tractor. They're very comfortable to wear.
Fits great and dampens the noise from my tractor down to an acceptable level. 👍
Very comfortable fit. Purchased for use in indoor range, works like a champ. Very satisfied.
Very comfort
I purchased these to assist in mitigating external sounds while having to spend time in a large, noisy and tourist-filled city. They really do the trick in muffling sounds thus allowing for less nervous-system overwhelm. Although it would be great if the ear muffs themselves were a tad more slimline, they are still stylish enough to wear out in public without people asking me if I need directions to the nearest gun range. Also want to mention that I have a 7 5/8ths head, and these fit great without the strap bearing down on the top of my skull (which would be a nightmare). Fellow autists, when your loops don’t cut it, these might be your answer.
The actual earmuffs themselves were too small for my ears unfortunately, but customer service was good and I appreciate that!
The xl are a lot better fit than the regular size ear muffs. First ordered the regular size ear muffs and they're great but a little short. Felt like they were picking up a little bit on the bottom of my ear. Definitely recommend them.
These fit right over my husbands hearing aids. He likes the very much.
Big enough
I wear hearing aids, so was looking for over the ear hearing protection to use while wearing them. I needed something that I could put on for quick hearing protection without having to remove the hearing aids and change to ear plugs. These are big enough that they don’t smash my ears and allow some extra room for the hearing aids.
Very effective.
Work well but key for me was xl size. My other sets were all a bit tight but these are very comfortable
High quality and comfortable!!
Excellent noise reduction while using the muffs with my zero turn lawnmower. Haven't had a chance to get to the range yet, but I don't expect any surprises shooting my 7mm Remington Magnum or 30-06 rifles.
They fit good
Perfect fit. Great price
These actually are adjustable to fit my husband's large head. He says they are very comfortable and work well when on the tractor. Thank.you for a good product.
Picked up a set of XL for working long shifts at a wood mill and using these in conjunction with Moldex Sparkplugs. Much better than the previous other brand earmuffs I had been using.
the ear muff is still not big enough.
Excellent for hearing protection, but barely fits. Definitely not XL (EXTRA LARGE)
My husband has a big head. The XL ear protection doesn't give him a headache.
I have a unique use. I'm learning drumming as am adult. My ears have taken some abuse over the years so I'm invested in keeping what heating I have left. I wear In Ear Monitors (IEMs) when I practice listening to the drums and music I'm playing with through the IEMs which has up to 36 db of protection. I wear the DDs over the IEMs for extra protection. When I'm playing I can listen to the music and my drums mixed in at very safe low levels, even if I'm rocking out. I'm grateful for your product. It is quite comfortable, too. I night the XLs they fit well. Thank you!
These are the best hearing protection. I go yo alot of Nascar races, and they are better than anything I've tried before. Yes even inside Bristol Motor Speedway. I recommend these to anyone. ! Size is good and comfortable to wear even with a baseball hat.
The best you can get. I tried home Depot, amazon, Lowes and these have the highest noise canceling capabilities and the best price. If you found these look no further, you want these. So quite, for loud or soft sounds, all different tones they just rock. I got extra large cuz my dome is on the bigger side and these fit perfect not too tight not too loose. Plus they have the nice cushions on the headband part. Really comfy. Would recommend 10/10
Perfect fit. They work great as hearing protection when doing woodworking!
